A new study on sources of PM2.5 in India has been released by Greenpeace and the Air-Weather-Climate (AWC) research group at Louisiana State University. The report is entitled Source Apportionment, Health Effects and Potential Reduction of Fine Particulate Matter (PM2.5).

The top four sources for PM identified in this analysis include coal-fired power plants, industrial emissions, use of solid fuels at the household level and brick kilns. Other key observations include:

Concentrations of PM2.5 were highest in the Indo-Gangetic region, including northern and eastern India. PM2.5 concentrations were higher during winter and lower during monsoon season.
